Hi.
00:02
Now in this question we are asked how many outfits can be put together if we have six shirts, four pair of pants and three pair of shoes.
00:13
Three pair of shoes.
00:15
So now how many outfits can be put together? now there are six ways to choose a shirt and there are four ways to choose a pant and there are three ways to choose a pair of shoes.
00:27
So the total number of ways becomes 70.
00:31
So in 72 ways we can choose shirts, pants and a pair of shoes.
00:39
Now the question is six digit numbers can be formed using the number one two three four five six without any repetition.
00:53
So how many numbers can be formed using the six numbers so this can be done in six factorial ways and six factors is equal to 720.

Now in next part, we have been asked how many different ways can the name justin.
01:13
J -u -s -t -i -n -a.
01:17
Justin b arranged.
01:19
So now this is a 1, 2, 3, 4, 5, 6, 7 letter word with no repetition.
01:26
So this can be done in 7 factorial ways...
